IMPROVEMENT IN ROLLS FOR THE MANUFACTURE OF SUCKER-ROD JOiNTS.

. Specification forming part of Letters Patent No. 192,054., dated J une19, 1877; application filed May 16, 1877. I

To all whom it may concern Be it known that I, JOHN (JAIN, of Sandy I.Lake, in the county of Mercer and State of Pennsylvania, have inventedcertain new and useful Improvements in Rolling-Mills; and I do herebydeclare the following to be a full,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in rolling-mills for themanufacture of sucker-rod tered A and B, are mounted in suitablestandjoints; and consists in a system of ro'llsof such construction thatthe metal may be introduced between the rolls while in motion, and by alateral movement of the bar or blank the same is readily introducedbetween the working-faces of the rolls and reduced to the desired form.

My invention further consists in a system of rolls, one. of which hasraised workingfaces, which engage with the working-faces of the oppositeroll, while each roll has a plain surface leading to its respectiveworking-face to allow the metalto be inserted by a lateral movementwhile the rolls are in motion.

a My invention further consists in a system' of rolls, one of which hasa raised eccentric rib formed thereon, which engages with a rectangulargroove formed between collars on the opposite roll, the eccentric riband one of i said collars formed with a section cut away on a plane'withthe rolls, whereby the metal may be introduced by a lateral movementwhile the rolls are in motion, and rolled out to form a tapering bar orstrap.

My invention further consists in a system of rolls, one of which has araised eccentric rib provided with a convex working face, which engageswith a groove formed between collars on the opposite roll, said grooveformed with a concave working-face, the eccentric rib and one of saidcollars cut away on a plane with the rolls, whereby the metal may beintroduced by a lateral movement while the rolls are in motion, andreduced to a tapering bar of concave-convex form in cross-section. v

My inveutionfurther consists in the combination, with asystem of rolls,one of which has raisedworking-faces, and the other provided withworking-faces formed between collars on the roll, a section of theraised working-face and one of the collars being cutaway on a plane withthe rolls, of a laterally-moving guide-frame extending between therolls, whereby the metal may be introduced between the rolls while inmotion, and by means of the guide-frame carried between theworking-faces of the rolls.

Referring to the drawings, Figure 1 is a view in perspective; Fig. 2, aview in longitudinal vertical section and Fig. 3 represents the tworolls detached from the mill.

The upper and lower rolls, respectively letards, and are formed one withgrooves, and the other with raised working-faces or eccentric ribs,whereby the'two rolls are adapted .to roll the straps on sucker-rodjoints. The

upper roll is provided with the eccentric IlbS D, extending partiallyaround the roll, but leaving plane smooth surfaces f on the same, ofsufficient width to allow the metal bar to be operated upon, to be movedlongitudinally of the roll when this plane surface is opposite the lowerroll. Withtherollin g grooves, respectively lettered D and E, the samebeing located between col-- lars H H Collars H are cut away or extendonly partially around the roll, to constitute openings d and e on aplanewith the rolls,

whereby the bar may be inserted between the rolls while in motion ateither the portion F or G of the roll, and by a lateral movement of theblank or bar it isinserted between the working-faces of the rolls andreduced by the.

same.

Any suitable guide-frame is placed between the two rolls, and serves toshift the metal bar from the plane portions F G of the roll through theconnecting openings into therolling grooves.

In the form of guide given, by way of example, in the present instance,a series of crossbars, H, are supported on longitudinal strips, whichlatter have horizontal sliding movement as they are operated by thefoot-treadle h in one case, and the weighted lever-arm. K in the othercase. The rock-shaft L has an arm, l, secured thereto.

arm Z engages in the diagonal guideway m, which latter is attached tothe sliding plate M. Pressure being applied to the treadle, operates tomove the shifting-guide H in a nron.

This lower roll B is formed The upper end of 2 aeaosa lineof directionaway from the rolling grooves,

while upon 'the removal of this foot-power the weighted lever throws theguide in the opposite direction or toward the said grooves.

The rolls being driven by any suitable means so as to roll the metaltoward the side of the mill where the operator stands ready to shift thesliding guide, the bar of iron is introduced first between the rolls atthe plain por-- tion F until a suitable length thereof is between therolls, which, by way of illustration, is about six inches of a bar whosecross-section is approximately one-h alf-by seven-eighths of an inch.

This bar is permitted to be thus introduced by the workman operating thetreadle which moves the sliding guide, so as to admit the bar, asdescribed. Upon removal of power from the treadle the weighted lever-armoperates to cause the guide to bear with side pressure against the bar,so that when, under the revolution of the rolls, the transverse openingd comes to the top of its roll, the side bearing against the bar willautomatically throw it through this connecting opening into the groove1). The operation of the eccentric rib G in conjunction with therectangular working-face D of the opposite roll serves to spread theiron out laterally and reduce it to a tapering form. A similar operationupon the opposite end of the same bar repeats the former result, and apartial or incomplete strap is rolled upon both ends of the bar.

The bar is then presented to the action of the second or finishing passE, .in a similar manner. The strap on one end is introduced into theplain portion G of therolls while the mill is still running, and whenthe opening 0 comes to the top of the roll the strap is shifted into thegroove E, formed with a curved working-face, and the same is rolled outof this pass finished. The. strap on the other end is subjected to thesame process, when the middle portion of the bar not operated upon, andstill reserving its original section, is ready to be cut centrallynearly in twain, bent over, and welded together to form the suckerrodjoint complete.

By thus constructing the rolls the metal is introduced between themwhile they are in full revolution, and is automatically thrown into theworking-grooves, rolled, and finished complete and the operation may becarried on indefinitely for any number of straps without stopping or inanywise interfering with the constant revolution of the rolls.

The eccentric form of the ribs 0 on the up per roll serves to roll outthe straps with tapering ends, and no vertical adjustment-or closing ofthe rolls is required in orderto form the same.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is I l. A rolling-mill consisting,essentially, in a system of rolls, one of which has a raisedworking-face extending only partially around the roll, and the other agrooved working-face bordered by collars extending above the plane ofthe roll, one of said collars extending only partially around the roll,whereby the blank may be inserted between the rolls while in motion, andby imparting lateral movement to the blank the same may be insertedbetween the working-faces of the opposite rolls, substantially asdescribed.

2. In a rolling-mill, the combination, with a I roll having an eccentricrib formed thereon, the same extending only partially around the roll,of an opposite 'roll provided with a working-face bordered by collarsextending above the plane of the roll, one of said collars extendingonly partially around the roll, substa'ntially as described.

3. In a rolling-mill, the combination, with a roll having an eccentricrib provided with a convex working-face, said rib extending onlypartially around the roll, of an opposite roll provided with aWorking-face bordered by collars extending above the plane of the roll,one of said collars extending only partially around the roll,substantially as described.

4. In a rolling-mill, the combination, with a roll provided with aneccentric rib having a convex working-face, said rib extending onlypartially around the roll, of an opposite roll, provided with a concaveworking-face bordered bycollars extending above the plane of the roll,one of said collars extending only partly around the roll, substantiallyas described.

5. The combination, with a roll provided with the eccentric ribsextending only partly around the roll, of a roll having flat and concaveworking-faces, each face of which is bordered by a pair of collars, oneof the pair ex tending only partly around the roll, substantially asdescribed.

6. The combination, with a pair of rolls, one of which is provided witheccentric ribs extending only partly around the roll, while the other isprovided with working-faces bordered by collars, one of the-collarsadjacent to each working-face extending only partly around the roll, ofa laterally-moving guide, a portion of which is located between theplain surfaces on the rolls, substantially as described.

7. A pair of rolls, one having eccentric ribs extending only partlyaround the roll, and the other provided with working-faces bordered bycollars, one of the collars adjacent to each working-face extending onlypartly around the roll, in combination-with a laterally-moving guide,and a rock-shaft having a treadle and weigted arm or lever securedthereto, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this11th day of May, 1877.
